DESCRIPTION

The unichars program reports which characters match all selection criteria anded together.

A criterion beginning with a square bracket or a backslash is assumed to be a regular expression. Anything else is a Perl expression such as you might pass to the Perl grep function. The $_ variable is set to each successive Unicode character, and if all criteria match, that character is displayed.

The numeric code point is therefore accessible as ord.

The special token NAME is set to the full name of the current code point. Also, the tokens NFD, NFKD, NFC, and NFKC are set to the corresponding normalization form.

By default only plane 0, the Basic Multilingual Plane, is examined. For plane 1, the Supplementary Multilingual Plane, use --smp. To examine either, specify both --bmp and --smp options, or -bs. To include all valid code points, use the -a or --astral option.

Unless the --unnamed option is given, characters with any of the properties Unassigned, PrivateUse, Han, or InHangulSyllables will be excluded.
